Higher ratedRanked #3 in Best Adjustable Kettlebells

Bells of Steel Adjustable Kettlebell

4.5

$210as of May 19

The Bells of Steel Adjustable Kettlebell is the competition-style pick — IKFF-compliant 35 mm handle, steel shell, and 41 weight settings from 12 to 32 kg with 0.5 kg micro-loading. For lifters who are serious about kettlebell sport or who progress past the 40-lb ceiling that most adjustables top out at, this is the bell that scales with you. The trade-offs are price and adjustment speed; everything else is a clear upgrade over the budget tiers.

Strengths

— Full 12-32 kg range (about 26-70 lb) — widest in this round-up
— 0.5 kg micro-loading — 41 possible weight settings
— Steel shell with iron plates — competition feel, no rattling

Watch-outs

— Most expensive pick here at $280
— Heavier than the Bowflex SelectTech 840 or PowerBlock at all weight levels
— Adjustment is slower than the Bowflex SelectTech 840's dial

Ranked #5 in Best Adjustable Kettlebells

Yes4All Adjustable Kettlebell

4.2

$60as of May 19

The Yes4All Adjustable is the value pick — about a third the price of the REP Fitness and nearly half the Bowflex SelectTech 840. Cast iron handle plus disc-and-spacer construction means it feels more authentic than plastic-shell alternatives in this price tier, and the 20-40 lb range covers most beginner programming. The trade-offs are adjustment speed and brand support, but for a sub-$60 entry-level option that lets you try kettlebell training without committing $200, it's hard to beat.

Strengths

— Cheapest adjustable kettlebell in this round-up by a wide margin
— Cast iron handle with steel components — better than plastic-shell budget alternatives
— 20-40 lb weight range covers most beginner programming

Watch-outs

— Slower adjustment than the Bowflex SelectTech 840 dial or PowerBlock pin
— Cast iron is less durable on drops than the Bells of Steel steel shell
— Heavier increments (4.6-6 lb per disc) vs Bells of Steel's 0.5 kg micro-loading

How they stack up

Bells of Steel Adjustable Kettlebell

Widest weight range and finest increments of any pick here — beats the REP Fitness on range and the Bowflex SelectTech 840 on ceiling (32 kg vs 18 kg). Loses to the Bowflex SelectTech 840 on adjustment speed. Steel-and-iron build is more durable than the Bowflex SelectTech 840's plastic but heavier to handle than the Yes4All.

Yes4All Adjustable Kettlebell

Cheapest pick by far — significantly under the Bowflex SelectTech 840, PowerBlock, REP Fitness, and Bells of Steel. Cast iron build is a real advantage over the Bowflex SelectTech 840's plastic shell at this price. Loses to every other pick on adjustment speed and weight ceiling.
